I tried using some chi wi'll trying to do some electro and aero and it seems to work.. but i dont know cuz it could just be the fact that its taking my mind off my intention which seems to be one of the bigger obsticels in doing it....puting it in the back of your mind instead of the front.
I've had access to circulating Qi for nearly seven years now. You'll know when you are accessing it through experience; (I have a tingling sensation in the legs and arms, stronger int he legs; as if being jolted with light electricity) explaining with words is a challenge because it is a subtle energy, and the effects are not instant most of the time. I integrate forms of Qigong into my martial arts training.
As for using it to amplify or focus your ability...Qi itself is the energy you're accessing to manifest your kinesis (I recommend reading about Dr. Yan Xin, EHF and his Qigong research. He explains scientifically the traits of Qi, how it functions as an "energy of information).
Harnessing your Qi starts with specific breathing methods (inhaling and holding the breath for 4 seconds, then exhaling for 4 seconds, etc.) and your concentration on those breaths. Next is visualization, where you imagine your Qi circulating through meridians (mind leading the Qi). Once you train yourself to access your Qi more efficiently, you won't have to redirect your intentions; you'll be able to heat or "cook" your Qi while intending to use your kinesis.
a good way to begin feeling your chi is to do what the other guy said and also try directing your inhaling breath to certain parts of your body, preferably the hands to start off with. Inhale and have your breath move down to your arms then to your hands. this is how I learned.
